Description

Technical Field

[0001] The utility model relates to the technical field of elevator rope grippers, in particular to a device for detecting an elevator rope gripper. Background Art

[0002] An elevator rope gripper is an important safety device for an elevator system, aiming to ensure that in the process of elevator operation, if an abnormal situation occurs (such as elevator overspeed or rope breakage, etc.), the lifting rope can be clamped in time to prevent the elevator from falling freely, thus ensuring the safety of passengers.

[0003] During the use of an elevator, it is necessary to periodically detect whether the function of the elevator rope gripper is normal to ensure the safety of the elevator car operation. Therefore, a device for detecting the elevator rope gripper needs to be used for detection. For example, in the prior art, the Chinese patent publication number "CN221370061U" discloses a device for detecting the function of an elevator rope gripper, including a base, a fixed block is fixedly installed on the top of the base, a spring is fixedly installed on the right side of the fixed block, and a fixed seat is fixedly installed on the top of the base. The pin column is inserted into the pin holes on both sides of the clamping head. By the elongation of the first electric telescopic rod, the connecting rod can be driven to move along the sliding groove, so that the pushing seat drives the pin column to pull the clamping head, causing the spring to undergo elastic deformation. By rotating the second locking screw rod, the positioning plate squeezes and clamps the detection rope in the clamping seat for fixation. By the contraction of the second electric telescopic rod, the pin column is pulled out of the pin hole, and under the elastic action of the spring, the clamping head is driven to reset, so as to simulate the high-speed running state of the detection rope and detect the function of the elevator rope gripper, and detect whether the elevator rope gripper can quickly cut off the power supply of the elevator to ensure the safety of people's lives and property.

[0004] In specific operations, by the method of fixing the clamping head through a pair of electric telescopic rods, after long-term use, the electric telescopic rods need to be maintained and replaced, resulting in an increase in detection costs. And the method of fixing the detection rope by the positioning plate and the clamping seat is not stable, and the situation that the detection rope breaks away due to insufficient clamping may occur, and the practicability is poor. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art and propose a device for detecting an elevator rope gripper.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Referring to Figures 1-5 , a device for detecting an elevator rope gripper includes a detection table 1, a sliding seat 2 is fixedly installed on the top of the detection table 1, a clamping seat 3 is slidably connected in the sliding seat 2 through a guiding groove 21, a driving member 4 for driving the clamping seat 3 to move is arranged at the bottom of the detection table 1, and a clamping part 6 is fixed on the top of the clamping seat 3 through a clamping assembly 5;

[0024] Wherein, a separating member 7 is provided in the guiding groove 21, and the separating member 7 is used to control the clamping assembly 5 to unlock the clamping portion 6, so that the clamping portion 6 loses the fastening force, and the clamping portion 6 is used to connect the detection rope 8.

[0025] Furthermore, the driving member 4 includes a cylinder 41 fixedly installed at the bottom of the detection table 1. A through groove 42 is formed in the guiding groove 21, and a guiding column 43 is fixedly installed. The clamping seat 3 is slidably connected to the guiding column 43, and a connecting block is slidably connected to the bottom of the clamping seat 3 in the through groove 42. The shaft end of the cylinder 41 is fixedly connected to the connecting block.

[0026] In this embodiment, when the clamping seat 3 fastens the clamping portion 6, the cylinder 41 is used to drive the clamping seat 3 to move, and then the clamping portion 6 is used to adjust the length of the detection rope 8.

[0027] Wherein, after unlocking the clamping portion 6, the reset spring 12 is used to pull the detection rope 8 back to its original position, so as to simulate the high-speed running state of the detection rope 8, which is convenient for detection.

[0028] It should be noted that one end of the detection rope 8 is fixedly connected to an object for bearing weight, and the other end is connected to an elevator rope gripper through the traction wheel 61.

[0029] Furthermore, the clamping assembly 5 includes a receiving plate 51. A receiving groove 52 is formed at the top of the clamping seat 3, and clamping jaws 53 are slidably connected to both sides of the receiving groove 52 inside the clamping seat 3. A pair of positioning columns 54 are provided on both sides of the clamping jaws 53. The receiving plate 51 is arranged between the pair of clamping jaws 53 through avoidance grooves at both ends, and both sides of the receiving plate 51 abut against the positioning columns 54. One end of the extending clamping portion 6 is arranged in the receiving groove 52 and is fastened by the pair of clamping jaws 53.

[0030] More specifically, a protruding portion 55 is provided in the receiving plate 51. A spring 56 is fixedly connected between the bottom of the protruding portion 55 and the clamping seat 3, and the top of the protruding portion 55 extends downward to form a positioning groove 57. A cam 58 is rotatably connected to the clamping seat 3 through a shaft end. The cam 58 can abut against the protruding portion 55 and be engaged in the positioning groove 57. Guiding inclined surfaces are provided on both sides of the positioning groove 57.

[0031] It is worth mentioning that a pair of the clamping jaws 53 are in a columnar structure, and pressing plates are fixedly installed between the opposite sides of the tops thereof. The clamping part 6 is fastened by the cooperation of the pair of pressing plates and the receiving groove 52. Among them, a pair of clamping grooves are formed in the periphery of the extended end of the clamping part 6. The clamping grooves correspond to the clamping jaws 53. The clamping grooves provide a movement amount for the clamping jaws 53, ensuring that when the cam 58 engages with the positioning groove 57, the clamping jaws 53 will not tightly abut against the clamping part 6 in advance, avoiding jamming.

[0032] Specifically, the cam 58 is rotated by the rotating shaft. While rotating, the cam 58 abuts against the protruding part 55, and then drives the receiving plate 51 to drive the pair of clamping jaws 53 to move downward. The cam 58 is engaged in the positioning groove 57, and under the upward supporting action of the spring 56, the protruding part 55 fixes the cam 58 through the positioning groove 57.

[0033] Generally speaking, a fixed seat 11 is fixedly installed on one side of the top of the detection table 1 and located at the side of the sliding seat 2. The clamping part 6 is slidably connected with the guiding column 43, and a return spring 12 is fixedly connected between the side surface of the clamping part 6 and the fixed seat 11.

[0034] In addition, the separating part 7 includes a connecting rod 71 fixedly installed with the shaft end located outside the clamping seat 3. A wedge-shaped rod 72 is fixedly installed in the guiding groove 21. The wedge-shaped rod 72 abuts against and slides with the connecting rod 71.

[0035] It should be noted that an avoidance groove is provided at the bottom of the clamping seat 3 to avoid jamming the wedge-shaped rod 72. A guiding inclined surface is provided on one side of the wedge-shaped rod 72. After the clamping seat 3 moves to a certain position, the connecting rod 71 abuts against the guiding inclined surface. And as the clamping seat 3 gradually moves, the connecting rod 71 rotates under the abutting action of the wedge-shaped rod 72, and then the cam 58 disengages from the positioning groove 57, and the pair of clamping jaws 53 move upward under the action of the spring 56.

[0036] Finally, a traction wheel 61 is rotatably connected to the extended end of the clamping part 6. A detection rope 8 is sleeved on the periphery of the traction wheel 61. The detection rope 8 is used to connect an elevator rope gripper.

[0037] Working mode; during work, the extended end of the clamping part 6 is placed in the receiving groove 52, and then the cam 58 is rotated by the rotating shaft. While rotating, the cam 58 abuts against the protruding part 55, and then drives the receiving plate 51 to drive the pair of clamping jaws 53 to move downward to fasten the clamping part 6. The cam 58 is engaged in the positioning groove 57, and under the upward supporting action of the spring 56, the protruding part 55 fixes the cam 58 through the positioning groove 57;

[0038] The detection rope 8 is sleeved around the periphery of the traction sheave 61 and connected to the elevator rope gripper. The air cylinder 41 drives the clamping seat 3 to move. After the clamping seat 3 moves to a certain position, the connecting rod 71 abuts against the guiding inclined surface, and as the clamping seat 3 gradually moves, the connecting rod 71 rotates under the abutting action of the wedge-shaped rod 72, and then the cam 58 disengages from the positioning groove 57, and a pair of clamping jaws 53 move upward under the action of the spring 56;

[0039] While a pair of clamping jaws 53 move upward, the clamping portion 6 quickly slides back to its original position under the action of the return spring 12, and then the working state of the detection rope 8 is detected.

[0040] As mentioned above, it is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
